Bluesky has made a sort of retro hyper +2010s-Tumblr2. I don't know how bluesky grew, but I think a lot of their growth was probably courting this very crowd, initially at least, before reaching a network effect and getting more normies and normal/sensible lefty types (who often actually find the place unbearable and leave).
I don't know who, or what group Judas goated that group of humans onto that platform, but they did a service for all humanity by bringing them somewhere else. Well played Jack, well played
